SPRING SHADE-ROLLER.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application led January 25, 1918. Serial No. 213,684.

To all wwm t may concern:

Be it known that I, WILLIAM MARION LowREY, a citizen of the United States, residing at Pomona, in the county of Los Angeles, State 0f California, have invented a new and useful Spring Shade-Roller; and I do hereby dec-lare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved spring shade roller, and an object of the 1nvention is to provide a simple and efficient shade roller of this kind comprising two sections, a wood body section and a metal tubular section, which is telescopically fitted to the body section and secured by screws, the

spring tensioning means for the roller being mounted in the tubular section.

A further object of the invention is the provision of improved .spring tensioning means consisting of a pin or shaft rotatably mounted concentrically in the end walls of the tubular section and a heliX spring, one end connected to said pin or shaft, and its other end anchored to one end wall of the tubular section.

A further object of the invention is to provide an improved spring tensioned shade roller of such improved construction as not to require winding of the spring.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings and claimed.

In the drawings Figure. 1 is a view in elevation of the improved shade roller as mounted in brackets of a portion of a window frame.

Fig. 2 is a view of the shade roller on an enlarged scale showing one end in section, and the other end in elevation and broken away and partly in section.

Fig. 3 is an end view of the shade roller.

Fig. 4 is a detail perspective view of the pin or shaft that is carried in the tubular section of the roller.

Referring more especially to the drawings 1 designates the wood body section, and 2 the tubular metal section. A conventional form of disk plate 3 is secured on the outer end 4 of the body wood section by means of the spur pin 5, which is provided with lugs 6, to prevent the spur pin from turning. This plate 3 is provided with an axially alined lug 7 projecting from the outer face of the plate, to engage one of the brackets 8 carriedl by the window frame 9. The inner end of the wood body section has a reduced part 9 adjoining a shoulder 10. The inner end of the tubular metal section has an extension annular flange 11,- which telescopically fits the reduced part 9a of the wood body section, there being screws 12 arranged as shown to secure the two sections together.

The tubular metal section 2 comprises the main part 13 and the end part 14, which is provided with a disk wall 15 constituting the end plate of the outer end of the tubular section. The endpart 14 has a reduced portion 1G fitting telescopically into the part 13, there being screws 17 for fastening the two parts together. A suitable shaft or pin 18 is provided, and has one end mounted in a bearing 19 of the end wall 2O 'of the tubular section and its other end in a bearing of the disk wall 15. This pin or shaft adjacent its opposite ends is provided with diametrically opposed radial lugs 21 and 22, so engaging the inner adjacent faces of the walls 15 and 20 as to prevent excessive axial movement of the pin or shaft. However, these lugs do not by frictional contact with said walls prevent easy rotation ,of the pin or shaft. A. helix spring 23 is mounted upon the pin or shaft. in any suitable manner to the wall 15 at 24, while its other end is passed through and secured to the pin or shaft 18 at 25. The outer end of the pin or shaft has a rectangular portion 2G to engage a correspondingly shaped bearing of the other bracket 8 of the window frame, thereby preventing the shaft or pin from turning, and allowing the roller to turn on the pin. The end wall 15 has pivoted thereon at points 2T diametrically opposite each other spring tensioned pawls 2S, which are designed to engage the teeth of the ratchet 2S), which is secured by a pin 30 to the shaft or pin 1S, thereby preventing rerolling of the shade after the roller has once been tensioned by the spring. Vith this form or construction of roller and spring and its mounting, it is unnecessary to wind the spring, when the roller is mounted in the brackets 8.

The'invention having been set forth what is claimed as new and useful is 1. A. shade roller, comprising a wood body One end of this spring 23 is anchored v ioo Section enel e tubular metal Section, means :for axiaiiy uniting the tivo Sections7 said 'uhului section having opposite end Welle :i Shaft pin mounted in axially alined healings of sind Walls, :i helix spring in the tuhulai' seeion und coiled about the Shaft loinH one end of the helix spring being connected to the shaft pin, und the othel end to one of the end Walls of the ubului seeion5 ineens struck up from the shaft pin near its opposite end und cooperating with the end Walls of the tubular Section, to prevent :miei movement of the shaft pin, seid tubular seotion consisting o two parte, means for telescopieullj/ uniting said parte, and L puivi. and ratchet connection between the tubulu section and the shaft pin.
